A recipe calls for 4 cups of flour. Lauren wants to make 20% more servings than the recipe makes. Which expression represents ho

ale4655 [162]

C. 6/5 * 4

6/5 = 1.20 where .20 represents the 20% increase in serving.

1.20 * 4 = 4.8 is the total cups of flour needed to increase serving by 20%

4 is the 100% ; the desired increase is 20%; therefore: 100% + 20% = 120% based on 4 cups. So, 120% ÷ 100% = 1.2 * 4 = 4.80 cups

elena55 [62]

Answer:

$9.00

Step-by-step explanation:

Given that $1.8 is 20% of the breakfast cost.

-We can use proportions to find the 100% cost of the breakfast before the tip.

-Let x be the full breakfast cost:

$0.2=1.8\\1.0=x\\\\0.2x=1.8\times 1.0\\\\\\x=\frac{1.8}{0.2}\\\\=9$

Hence, the full breakfast cost is $9.00 before the tip.
